Obstetric cholestasis

Does anyone have any experience with this?

The soles of my feet are SO itchy, but I also itch on my arms, legs, back, and scalp.

I have some itching attacks throughout the day, but it’s relatively mild and easier to handle. Then at night, all hell breaks loose and I’m using hairbrushes and anything sharp to tear at my feet and skin. Eventually it stops for awhile and I can fall asleep.

I guess my question is, can the itching be intermittent or does it have to be constant? I’m going to call my OB first thing in the morning, but haven’t been able to find much info on itching that comes in waves. I’m 35+0.
